About

GPT-Realtime-2 is OpenAI’s voice model for live interactions where the model can keep the conversation moving while it reasons through requests, calls tools, handles corrections or interruptions, and responds in a way that fits the moment. It is built for a new class of voice apps that feel more natural, respond more intelligently, and take action in real time. GPT-Realtime-2 brings GPT-5-class reasoning to voice experiences, helping agents understand what someone means, track context, recover when a request changes, use tools while the conversation continues, and carry the conversation forward naturally. Developers can enable short preambles like “let me check that” so users know the agent is working, and the model can call multiple tools at once while making actions audible with phrases like “checking your calendar” or “looking that up now.” It also has stronger recovery behavior, longer context for agentic workflows, better retention of specialized terminology, etc.

About

Miso Labs builds emotive foundation models for voice, designed to help developers create voice agents that feel fast, warm, and human instead of robotic or delayed. Its flagship model, Miso TTS, is an 8-billion-parameter transformer model for state-of-the-art emotive speech and dialogue generation, with open source weights available on Hugging Face and API access coming soon. Miso is built for real-time conversational voice, responding in 110ms to preserve natural flow and avoid the awkward pauses common in AI voice agents. It supports one-shot voice cloning, allowing users to clone a voice from a ten-second audio clip while keeping the agent’s voice consistent from the first second of a call to the last. Miso Labs also emphasizes local and sovereign deployment, with open source models built for local use and on-premises hosting and support available for enterprise teams that need to keep sensitive data in-house.
